THE MATHEMAITC MODEL OF INTERIOR BALLISTIC AND SIMULATION OF THE WARSHIP TORPEDO LAUNCHER

针对火药发射的特点 ,利用开口系统热力学第一定律的方法 ,建立了以火药为工质的鱼雷发射装置内弹道数学模型 ,并进行了计算机仿真 .仿真结果与试验结果相比表明 。

In view of using the propellant charge in the torpedo launcher, this paper puts forward the mathematic model of interior ballistic with two periods by using the first thermodynamic law. Then, the simulation of the mathematic model is carried out. According to the comparison between the simulation results and the test results, this mathematic model is correct, and describes the torpedo’s motion law in tube accurately.
